DRYlNG-HOUSE.

Specification forming part of Letters Patent No. 57,117, dated August 14, 1866.

To all whom it 'may concern:

Be it known that we, H. B. GALLUP and CHARLES WOOD, of Watertown, in the county of Jefferson and State of Wisconsin, have invented a new and Improved Drying-House; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, inwhioh Figure l is a vertical section of our invention, taken in the line 00 Fig. 2; Fig. 2, a vertical section of the same, taken in the line y y, Fig. l.

Similar letters of reference indicate like parts.

The object of this invention is to obtain a house for drying lumber and other substances, which will be fire-proof and possess other advan tages hereinafter named over drying-houses now in use, or as at present constructed.

A represents the Walls of the structure, which may be of brick, stone, or iron, strengthened at the top by iron rods a, extending entirely across from outside to outside of the side walls.

The roof B may be of the same materia-l as the side walls and arched, having one or more pipes, C, passing vertically through its center, and extending about two feet above the arch. The pipes are designed to be furnished with dampers or caps, so that they may be opened and closed at pleasure.

The tloor of the structure is composed of iron bars b, (railroad-rails will answer,)v extending across from one side wall to the other, with their ends iitted therein.

The cellar D may be about seven feet deep below floor, or of a depth to admit a stove or furnace and horizontal smoke-pipe, and leave sufficient space above to avoid danger of igniting the contents by the stove and pipe.

The heat used may be either dry heat or steam, or both. If dry heat be used, the stove and pipe are placed in the cellar, as shown in red in Fig. 2. If heat from steam be used, the

steam may be superheated; or Waste-steam from a boiler or the cxhauststeam from an engine may be introduced into the cellar through suitable pipes.

The inner surface of the structure we design to have covered with a hard finish of waterlime or cement, in order to avoid the absorp tion of steam by the walls, (which absorption would be considerable if the walls were of brick,) and also to present a cold smooth surface for the condensation of steam.

We place one or more sets of gutters, E, of copper, tin, or other material, against the inner surfaces of the walls. These gutters extend entirely around the interior of the building, and extend through the walls and discharge outside. These gutters are designed to receive and convey outside the Water condensed on the inner sides of the walls and roof. We also place a suspended gutter, F, centrally under the roof to receive the water of condensation from the pipes C and carry the same outside.

By this arrangement and mode of construction a tire-proof drying-house is obtained and the contents of the house rendered safe while drying. If the contents should take tire the pipe O is then closed, and the re of course would soon be extinguished.

By preventing the absorption of moisture by the walls the contents of the house will dry evenly throughout. Economy in fuel is also obtained.

We claim as new and desire to secure by Letters Patent- A drying-house having its walls constructed of brick, stone, iron, or other fire-proof material, provided with a iiooring of metal bars, an arched roof provided with metal vent-pipes, and the interior surfaces of its walls provided with gutters, all arranged substantially in the manner as and for the purpose set forth.
